APRIL 2021 AFTERMARKET 39 Left: MAHLE ADAS kit in the workshop recalibration is required, much like a service indicator light works, but that’s not always going to happen. Instead, through our training we work to educate garages and technicians about all the potential scenarios, typically across four brands, that commonly require ADAS recalibration. For example, completing something as routine as a cambelt or camshaft chain replacement may require the camera or radar sensors in the bumper to be reset, simply because a lot of the front end has been removed to access the mechanicals.We support this training by literally giving the trade the right tools for the job. A massive help is the functionality of our DS diagnostic tool, which takes away any element of doubt and efficiently empowers users with the information on what ADAS recalibration needs to be done.” In addition, and to help garages accomplish increasingly common ADAS recalibration, Delphi Technologies has recently launched its modular ADAS calibration kit. “It works seamlessly with the existing DS Diagnostic tablet and software,” said Phil “and provides an initial provision for 284 models with camera calibration and 146 models with radar calibration. More applications will continue to be added, too. Importantly, it also includes the two- day training course, enabling garages to quickly get up-to-speed and start the return on their investment.” Phil concluded: “There’s a lot for garages to learn about ADAS recalibration, particularly on the practical side, but it’s not something that the trade should shy away from. The support is there for them to maximise the potential revenue stream for their business and to complete ADAS-related tasks in the correct manner. Above all though, it must be recognised that it will become an essential service, not just because of the increase in demand but due to garages’ obligation to complete repairs that don’t compromise the safety systems of a vehicle.” Increasingly sophisticated There are a range of systems available. Looking at the technology, Bosch’s spokesman said: “Nowadays there are two fundamental families of sensor; radar, lidar or ultrasonic-based for distance and speed measurement, and, vision-based sensors for object detection and location. However, it is no longer the case that these sensors work independently, with a technology known as sensor fusion information from all types of sensors, together with mapping provided by GPS, can be combined to provided increasingly sophisticated levels of driver assistance. “Static calibration of radar-based systems, e.g. adaptive cruise control, typically uses a reflector at a known distance and angle for calibration, whereas the vision-based systems tend to use a board with a specific target pattern for calibration. What is common to all forms of static calibration is the necessity to accurately position the calibration equipment in relation to the vehicle. All Bosch systems meet or exceed the individual vehicle manufacturers requirements for determining the vehicle centre line or geometric driving axis.” Calibration On calibration, Bosch’s spokesman said: “Correct calibration is vitally important to ensure the correct functioning of the system for safety and customer satisfaction. The overriding concern is one of liability. As with all work carried out by a workshop the liability for events which result from their actions will lie with the workshop. As many ADAS systems can be classed as safety critical the implications for the workshop are clear, even if ultimate responsibility for controlling the vehicle remains with the driver. Incorrect calibration of even a simple adaptive cruise control sensor may result in vehicle slowing unexpectedly by triggering from a vehicle in another lane, again causing customer dissatisfaction and a return visit.” Key factors There are some key factors which need to be in place to enable a workshop to carry out ADAS adjustment or calibration. For one, technicians have to be competent to carry out the work, making training a must: “ADAS training is available at a number of levels, with some brand- new online courses now available, enabling remote learning. The two- day IMI accredited ADAS Calibration course is now available as an online blended learning option, enabling the technician to gain exactly the same skills and qualification as the face-to- face version of the training. The course is complemented by a one-day Introduction to ADAS Systems and a newly-released Vehicle Safety Systems – ADAS half-day seminar.” For more information on Bosch Training, visit www.bosch-training- solutions.co.uk/gb/ Techs also need the right equipment.
